Hyperbaric Oxygen Chamber treatment isn’t a new fad…it’s been around for 50 years. This April 24, 1967, Newsweek article.
TREATMENT UNDER PRESSURE
“Hyperbaric oxygen chambers look like a huge submarine moored improbably to hospital basement floors. The resemblance is apt; patients undergoing open heart surgery in the chambers are given pure oxygen to breathe while the chamber pressure is raised to about three times normal concentration of oxygen-giving the surgeon more time to operate. Chicago’s Luthern General Hospital has three chambers ranging in size from 23′ to 41′ long; one contains a fully equipped operating room, another a six-bed intensive-care unit, and the third is used for research and isolation of patients with severe infections. Together they cost more than 1.1 million to install. In addition to heart surgery, hyperbaric therapy has proven its worth in the treatment of tetanus and gas gangrene, because the bacteria causing these diseases are killed by oxygen in heavy concentrations. Some researchers have found that hyperbaric oxygen treatments improve a stroke victim’s chances of recovery by compensating for the impaired blood supply to the brain; the chamber has also averted the need for amputation in patients with injuries or atherosclerotic deposits that cut off circulation to the arms or legs. Finally, they are widely used in operations to repair heart defects in infants, whose circulatory systems are often too tiny to be hooked to the tubes of a heart-lung machine.”
As you can see this treatment worked in 1967 and is still working today. However; you can now have a custom-built chamber in your home for less than the price of a new compact car.
